rtos selection
Hi,
Im using in my design PPC405 and considering which RTOS to use,
Im cosidering the following options VX-works and Green-Hills OS's.
Can anyone share with me his/hers thoughts between these two OS's.
Thanks,
Ben.
Re: Basic Memory-Map
Hi,
I believe that you can find some answers for this issue at the different datasheets of some MCU's (with 16 bit bus) or some processors. any device ussing a flash memory will describe you its memory architecture.
and some flash memory data sheets might be helpful as...
Hi kordix,
You are right, the command is "psect" not "psec, i saw that command at the hi-tech manual. it should direct the linker to reference to a specific program section. though i dont know how to use it correctly in order to separate my code into 2 parts at the program memory.
Im...
I saw a reference to the asm command regarding programming sections -> "psec" command, does anybody knows if using this command can solve may problem and how to implement this command into the code?

Hi,
I wans to separate my code into 2 parts, first part i want to write it at the following addresses : 0000H ÷ 07FFH and the other part satrting at 0800H address.
Im not familiar with the linker commands, can someone help me with it, i need to know what kind of commands i need to put inside...
Hi,
One more thing you should check is if the GND line is connected at you communication cable, i had this problem once and it solved the problem.

Re: PIC18X bootloader
Hi,
Im using the Hi-tech compiler for my programs.
usually, the code at these bootloaders files dont use the interupts for the uart nor for the timers. i would like to use the interupts (i think that this way the code is much more stable).
Any way, i have found the C...
Hi Asham,
You should define the byte you sending as an Unsigned char.
the asci table dec values are starting at 0x00, and the char variable type is from -128 to 127. the unsigned char is from 0 to 255 : therefor this type will cover all the asci table characters.
Good luck,
Ben.
pic 18x
Hi Rafael,
Thanks, im familiar with the Tiny Bootloader, i guess i didnt mention it earlier, im interested in a C code for the bootloader. (im not so familiar with the Pic asm commands).
Im likely to change the code of the bootloader in order to integrate it into my design. therefor...
Hi all,
Im trying to implement a bootloader for my PIC18 micro.
Can someone direct me, where can find information regarding the linker commands. i want to set the address of the main application right after the boot firmware.
Thanks, Ben.
Hi Gigi,
You didnt specify the type of FPGA or micro you are using,
You can use the JTAG lines (boundary scan) for testing and programing any device located on your board.
You can find information at the following standards:
IEEE 1532 (ISC)
IEEE 1149 (Boundary Scan)
anyway you can find...
